Document Summary

Econ 4710 aggregate economic analysis, spring 2012. Answers to midterm exam 1. Consumption is given by the equation c = 500 + Taxes (t) are equal to 1,000. Government spending is 600. This function exhibits: economies of scope, decreasing returns to scale, constant returns to scale, increasing returns to scale. [6 pts] consider a small island economy in the pacific ocean. Originally, this economy is isolated from the rest of the world (i. e. , a closed economy). Suppose that the equilibrium real interest rate in this economy is higher than the world real interest rate. Be specific to changes in national saving, domestic interest rate, investment, and net exports. In the closed economy, the economy stays at a, where sclosed = iclosed. Since domestic factors (e. g. , y, t, g) are not changed, national saving stays the same. As a result, nx = sopen iopen < 0. [5 pts] people in the economy revise their expected rate of inflation upward. r r.
